    The BGS Rock Classification Scheme (RCS) is a comprehensive classification scheme for all types of rocks and unconsolidated sediments worldwide. It is intended to be used for classification of single rock samples and can be used without any knowledge of field relationships. It has been designed for use by people with a wide range of geological knowledge; from experienced professional geologists to technicians and drillers. It also allows names to be assigned according to the level of information about the sample. The system if hierarchical, ranging from very simple names such as igneous rock to highly detailed names such as mugearite, that can only be applied after chemical analysis. Rock names can consist of a root name e.g. granite and several qualifiers that impart more information e.g. grey-biotite-bearing granite. The classification scheme has been implemented as a hierarchical dictionary of codes for all rock types. The classification scheme is described in BGS Research Reports 99-02, 99-03, 99-06. The BGS Rock Classification Scheme was devised between 1993 and 1996 in response to a need from the Digital Map Production System project.

    This dataset contains tabulated production, consumption and trade data on minerals in the UK together with authoritative commentary on current developments in the minerals industry. Data are supplied from official sources, companies and trade associations. Where data cannot be acquired, estimates are given. In addition to UK (country) data, statistics are also given at planning region level and, for certain minerals, at county level. Units of measurements are tonnes, kilograms or carats, according to commodity. Value is also provided for imports and exports. The information will be of value to all those interested in Britain's minerals. The data captured by BGS spans from 1973 onwards and is updated annually.

    High frequency (100 Hz) data from two horizontal induction coils measuring the Earth's magnetic field at the Eskdalemuir Observatory in the United Kingdom. The data covers the period from September 2012 to December 2012. Also included are examples of Matlab code and the frequency calibration files to convert to the raw data to SI units. Thumbnail spectrograms and metadata about the setup and equipment is also supplied.

    Scanned collection of seismological journals and offprints. The original collection was compiled by John Wartnaby. John Wartnaby was a curator at the Science Museum, London, and wrote a historical survey of seismology and scientific instruments. His accumulated papers consist chiefly of offprints and articles, and many older British Association seismological reports. The collection is part of the National Seismological Archive.

    Series of water/rock and water/mineral interaction experiments at a range of temperatures and pressures. Most experimental runs now held in Excel spreadsheets. All runs held as paper records in the laboratory. Analytical results also held in Excel format. Kinetic information held in Access database for a range of minerals. Also have several reference datasets in Hypercard and End Note.

    Old card index of quarries in England, Wales and Scotland dating mostly from 1939 to 1963: about 7000 cards, each referring to one quarry. England & Wales cards are arranged by BGS 1-inch (now 50k scale) geological sheet, Scottish cards by county. At best, cards indicate county, geol-sheet, rock type, name, grid reference, locality, owner, date of record and cross references to BGS samples.

    NIGL (NERC Isotope Geosciences Laboratories) is a comprehensive stable and radiogenic isotope laboratory facility that undertakes environmental, life, archaeological and earth science research, and educates and trains PhD students, in a collaborative research environment. This dataset contains a complete listing of projects undertaken by NIGL since its formation in 1987. It includes projects approved by the NERC Isotope Geoscience Facilities Steering Committee, projects with BGS, BAS and other NERC institutes, and commercial work.

    High frequency (100 Hz) data from two horizontal induction coils measuring the Earth's magnetic field at the Eskdalemuir Observatory in the United Kingdom. The data covers the period from January 2015 to December 2015. Also included are examples of Matlab code and the frequency calibration files to convert to the raw data to SI units. Thumbnail spectrograms and metadata about the setup and equipment is also supplied.

    The BGS Geoscience Thesaurus contains approximately 6000 descriptor terms for concepts in the geoscience and related subjects. Some entries have scope notes to further explain the term. The original source of the data was the Australian Mineral Foundation thesaurus of geoscience; some terms have been added or updated to suit BGS needs and the content will continue to be updated as required. The thesaurus includes synonyms to descriptor terms, hierarchical relationships, symmetric (see also) relationships and lapsed (deprecated) term replacements.

    Sometimes known as the "One-Inch Collection", this is an archival collection of rock samples collected by BGS field staff during surveys within England and Wales, arranged by 1-inch (or 50 K) scale BGS geological map sheet area. It was intended as a representative suite of the lithologies present in each sheet, although this was only partially achieved. Documentation is via archive of rock sample collection sheets (see COLLECTIONSHEETS) but is poorly coordinated at present.
